How to check when my Windows machine booted up.

If you want to check when you last booted your computer, you can find this information using the Command Prompt. To do this, press Windows+R, type cmd and press Enter .Once you have your Command prompt ready type in:

C:\systeminfo | find /i "Boot Time"

The Command Prompt will display the exact time and date that the PC was last booted. It can take the console up to a minute to find this information, so be patient if it seems like it’s taking a while.
